Summary

This study tests whether adding letrozole, a drug commonly used for breast cancer, to the standard medication misoprostol can improve the complete termination of second-trimester pregnancies (14-20 weeks). The trial will compare the combination against misoprostol alone in 80 women with a failed pregnancy. The main goal is to see if the combination leads to a higher rate of complete abortion, potentially making the process safer and more effective.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
letrozole combined with misoprostol
What this could lead to
If adding letrozole works, it could make second-trimester abortion procedures faster and more complete, reducing the need for additional surgical intervention.
What could go wrong
This is an early-phase trial with a small number of participants, so results may not be conclusive. Adding letrozole could also increase side effects without improving outcomes.
